There is a lot of jockeying going on right now folks!!
United & Continental have reached an agreement. USAir & United were close afew weeks ago.... so what does it all mean?
Well... lots of regional flights will be cancelled in markets that are over saturated with competition.... that goes for ALL airlines. That means less seats and higher prices. I've noticed that a lot of EARLY morning flights are being dropped.... so if you intend on flying an early morning connecting flight BEFORE your Aruba flight you should be watching it carefully.
Most folks are loyal to an airline for frequent flyer reasons.... that's just about all out-the-window. ALL of the carriers will be dropping/cancelling flights in various markets that they "share" with a pertner airline. (IE United/Continental/USAir) So I expect that having a "choice" of airlines form any major airport will begin to dwindle as time progresses!!
Suggestion IMO...... if you plan on using "frequent flyer miles".... you better book at 330 days, or close.... and don't mess around. I do expect the airlines to re-route at their convenience... (IE BOS/MIA/AUA) or similar. Good luck and I'm keeping a close eye on a lot of this! I just don't want to see folks get "whacked" at the last minute if I can help!!
